The Amprobe A-5000 A-frame ground fault locator is for use with the Amprobe AT-5000 cable and pipe locating system to find cable ground faults in power cables, telecommunications cables, and other sheathed cables without excavating or damaging the cable. The A-5000 has a liquid crystal display (LCD) with a bar graph and arrow that show the signal strength and direction of the fault to help pinpoint location of faults, compare faults, and find tree and pinhole faults in power cables. It can locate high- and low-resistance faults for finding very small pinhole faults to very large faults in ground that is very wet to very dry. The A-5000 detects either a 9.82 kHz or an 82 kHz frequency, for precise locating. It comes with two conductive pads and two washers for improving tracing results on dry, hard surfaces, such as concrete pavement. It operates on one 9V battery (installed) and has a battery charge indicator. The A-5000 ground fault locator weighs 4.4 lb. (2 kg) and measures 32 x 22 x 1 inches (810 x 560 x 25 mm, H x W x D). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; and D is depth, the horizontal distance from front to back).Pipe and cable locators, also called utility locators, find pipes, cables, and wires that are buried in the ground for determining where to excavate on a site and for locating buried fixtures in need of maintenance or replacement. Pipe and cable locators are used in electrical, plumbing, telecommunications, utility maintenance, construction, and home repair applications. They have a transmitter and a receiver and use active or passive methods of location. In active location, the transmitter induces a signal at a specific frequency either into the ground, where it"s picked up by buried utilities, or directly into a pipe, cable, or wire that is connected to the transmitter. As the signal is being transmitted into the buried utility, the receiver is passed over an area until it detects the signal and locates the buried pipe, cable, or wire. In passive location, the receiver searches for alternating current (AC) frequencies or radio waves emitted by energized cables, wires, and pipes without the need for a transmitter. Pipe transmitters, signal clamps, and grounding stakes can be used to help improve locator accuracy.Amprobe manufactures electrical testing equipment for commercial, industrial, and home use.
